its to work out if two triangles are the same in every way
A pyramid need not have any congruent sides.A pyramid need not have any congruent sides.A pyramid need not have any congruent sides.A pyramid need not have any congruent sides.
No, they are similar. They may be congruent, but they need not be.
The lengths of the sides need not be congruent. For example, consider a square and a rectangle.
One shape cannot be congruent: you need two (or more) shapes which can be congruent to each other.
To show that triangle ABC is congruent to triangle XYZ by the Side-Angle-Side (SAS) criterion, we also need to establish that the included angles are congruent. Specifically, we need to demonstrate that angle ABC is congruent to angle XYZ. With the two pairs of congruent sides (AB ≅ XY and BC ≅ YZ) and the included angle congruence, SAS can be satisfied.
SAS and SSS are congruent. SSA need not be.
No, because they need not be congruent.
no
yes, only the isosceles triangle has two congruent angles. But triangles don't need any congruent angles
They need not be congruent so the question is based on a fallacy.
Angle "A" is congruent to Angle "D"
trapezoid * * * * * It cannot be a trapezoid because that does not have four congruent sides. In fact it need not have even two congruent sides. The correct answer is a rhombus.
